Study Arms (2)

control group

NO INTERVENTION

Tourniquet would be tied to left upper limb of Patients who undergoing laparotomy for 30 minutes after the induction of anesthesia,but put no press on it. Other processes are consistent with conventional methods.

intervention

EXPERIMENTAL

1. After the anesthesia induction and before surgery,the patient's left upper limb was subjected to ischemic preconditioning. 2. At the beginning of anesthesia induction, 3 μg / kg / h of dexmedetomidine was infused and adjusted to 0.3 ug / kg / h after 10 min of infusion until 30 minutes before the end of the procedure. 3. Before the induction of anesthesia, the steel wire epidural catheter was placed in the T8-9 or T10-11 gap.

Procedure: Ischemic preconditioningDrug: DexmedetomidineProcedure: Patient-controlled epidural analgesia

Interventions

After the anesthesia induction and before surgery,the patient's left upper limb was subjected to ischemic preconditioning then patients received ischemic preconditioning.

intervention

At the beginning of anesthesia induction, 3 ug/kg/h of dexmedetomidine was infused and adjusted to 0.3 ug/kg/h after 10 min of infusion until 30 minutes before the end of the procedure.

intervention

Before the induction of anesthesia, the steel wire epidural catheter was placed in the T8-9 or T10-11 gap.The first volume of morphine 2mg + 0.2% ropivacaine + 0.9% saline 6ml, maintenance dose of morphine 18mg + 0.1% ropivacaine + 0.9% saline total 150ml. PCEA work with a continuous background dose of 2 ml/h with a single dose of 2ml/time, load 2ml, locking time 15min.
